【０００６】
【実施例】
本発明の実施例を図面により説明すると、１は中央に穴２のある穴開きヘッドレストであり、図示は省略するがウレタン等のクッション材の表面を表皮部材３により包囲する。本発明は、表皮部材３の縫製方法に関するものであり、表皮部材３は前側部材４と後側部材５と、前記前側部材４および後側部材５に夫々設けた窓孔６、７の間を連結する窓内周部材８と、前記前側部材４および後側部材５の夫々の下部に縫製する下面部材９とにより構成し、各部材は、夫々表面１０と裏面１１とを有し、理解を容易にするため、表面は格子柄（模様）として図示している（なお、格子柄は理解を容易にするためのものであり、各図において整合しないこともある）。また、前記表皮部材３はデザインにより前側部材４と後側部材５と、窓内周部材８と、下面部材９とを任意形状に分割形成してもよいが、その分縫着部分は増加し、本願は、これらの単位を基準として説明する。
【０００７】
しかして、前記窓内周部材８は長方形に裁断され、その端部１３を表面１０が内側になるようにして重ねて、縫着１４する。
次ぎに、後側部材５の下縁１５に下面部材９の後縁１６を重合させて縫着１７する。次ぎに、この後側部材５と下面部材９を図において上下反転させて、この状態の後側部材５の窓孔７の内周に筒状にした窓内周部材８の後側周縁１８を重合させて縫着２０する。
【０００８】
次ぎに、上向きになっている窓内周部材８の前側周縁２１に前側部材４の窓孔６の内周縁を重合させて縫着２２する。
この状態では、当然に、前側部材４と後側部材５は、その中央部分が窓内周部材８により連結され、前側部材４と後側部材５の夫々の裏面１１が相対峙し、その周縁が縫着されていない状態になる。
この状態で、左右の一方側、実施例では、前側部材４と後側部材５の各左側縁２３、２４を右側縁２５、２６に向けて折り、右側縁２５と右側縁２６の外側で前側部材４の左側縁２３と後側部材５の左側縁２４とを重合させて逢着２７する。この場合、前側部材４と後側部材５は左右中間の上側より側部下縁まで逢着２７し、この逢着２７により筒状になった前側部材４と後側部材５の下部の開口部２８より未逢着の前側部材４と後側部材５の部分を含めて裏返すと、通常状態の表皮部材３の左右中間の上側より左側部下縁まで逢着２７される。
【０００９】
次ぎに、前側部材４と後側部材５の未逢着の各右側縁２５と右側縁２６を既逢着２７の左側縁２３と左側縁２４に向けて折り、左側縁２３と左側縁２４の既逢着２７の外側で前側部材４の右側縁２５と後側部材５の右側縁２６とを重合させて逢着２９する。
この場合も、前側部材４と後側部材５は左右中間の前記未縫着分の上側より側部下縁まで逢着２９し、図示は省略するが前記と同様に、この逢着２９により筒状になった前側部材４と後側部材５の下部の開口部２８より全体を裏返すと、周縁が逢着された表皮部材３となる。
【００１０】
しかして、縫製された表皮部材３にステー３０を装着し、この状態の表皮部材３を金型にセットし、クッション材を発泡注入すると、穴開きヘッドレスト１が完成する。
この場合、ステー３０の装着は、ステー３０の周囲に各部材を縫製しながら行ってもよく、その順序は任意である。
【００１１】
また、実施例の前側部材４の下縁３１と下面部材９の前縁３２とは縫着されいないが、この部分が前記開口部２８となり、クッション材を発泡注入すると、クッション材により端末挟持されて処理される。
なお、図１〜図３において、実際の縫着部分は表面から見えない内側であるが、位置関係を表現するため、ヘッドレスト１の外側に縫着部分を示す符号を付している。したがって、この符号のみをもって、縫着部分は限定されない。
【００１２】
【作用】
次に作用を述べる。
後側部材５の下縁１５に下面部材９の後縁１６を重合させて縫着１７し、次ぎに、この後側部材５と下面部材９を反転させて、この状態の後側部材５の窓孔７の内周に筒状にした窓内周部材８の後側周縁を重合させて縫着２０する。
次ぎに、上向きになっている窓内周部材８の前側周縁に前側部材４の窓孔６の内周縁を重合させて縫着２２するから、前側部材４と後側部材５の裏面１１が相対峙しており、前側部材４と後側部材５の周縁が縫着されていない状態になる。
【００１３】
この状態で、前側部材４と後側部材５の各左側縁２３、左側縁２４を右側縁２５、右側縁２６に向けて折り、右側縁２５と右側縁２６の外側で前側部材４の左側縁２３と後側部材５の左側縁２４とを重合させて逢着２７するから、前側部材４と後側部材５の左右中間の上側より側部下縁まで逢着２７される。
そして、この逢着２７により筒状になるから、前側部材４と後側部材５の下部の開口部２８より未逢着の前側部材４と後側部材５の部分を含めて裏返すことができ、左右中間の上側より左側部下縁まで逢着２７された表皮部材３が得られる。
【００１４】
次ぎに、前側部材４と後側部材５の未逢着の各右側縁２５、右側縁２６を既逢着２７の左側縁２３、左側縁２４に向けて折り、左側縁２３、左側縁２４の既逢着２７の外側で前側部材４の右側縁２５と後側部材５の右側縁２６とを重合させて逢着逢着２９するから、表皮部材３は筒状になり、前側部材４と後側部材５の周縁は全部逢着される。
表皮部材３は筒状になっているから、開口部２８より全体を裏返すと、周縁が逢着された表皮部材３となる。
【００１５】

[0006]
【Example】
An embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a perforated headrest having a hole 2 in the center, and the surface of a cushion material such as urethane is surrounded by a skin member 3 although not shown. The present invention relates to a method for sewing the outer skin member 3, and the outer skin member 3 is formed between the front side member 4, the rear side member 5, and the window holes 6, 7 provided in the front side member 4 and the rear side member 5, respectively. A window inner peripheral member 8 to be connected and a lower surface member 9 sewn on the lower part of each of the front side member 4 and the rear side member 5, each of which has a front surface 10 and a back surface 11, respectively. For ease of illustration, the surface is illustrated as a grid pattern (pattern) (note that the grid pattern is for ease of understanding and may not match in each figure). The skin member 3 may be formed by dividing the front member 4, the rear member 5, the window inner peripheral member 8, and the lower surface member 9 into arbitrary shapes depending on the design, but the sewn portion increases accordingly. The present application will be described based on these units.
[0007]
Then, the window inner peripheral member 8 is cut into a rectangle, and the end portion 13 is overlapped so that the surface 10 is on the inside, and is sewn 14.
Next, the rear edge 16 of the lower surface member 9 is superposed on the lower edge 15 of the rear member 5 and sewn 17. Next, the rear member 5 and the lower member 9 are turned upside down in the drawing, and the rear peripheral edge 18 of the window inner peripheral member 8 formed into a cylindrical shape on the inner periphery of the window hole 7 of the rear member 5 in this state is formed. Polymerize and sew 20.

Next, the inner peripheral edge of the window hole 6 of the front member 4 is overlapped with the front peripheral edge 21 of the window inner peripheral member 8 facing upward, and is sewn 22.
In this state, of course, the front member 4 and the rear member 5 are connected at their center portions by the window inner peripheral member 8, and the rear surfaces 11 of the front member 4 and the rear member 5 are relatively inclined, and the peripheral edges thereof. Will not be sewn.
In this state, one of the left and right sides, in the embodiment, the left side edges 23 and 24 of the front side member 4 and the rear side member 5 are folded toward the right side edges 25 and 26, and the front side is outside the right side edge 25 and the right side edge 26. The left side edge 23 of the member 4 and the left side edge 24 of the rear side member 5 are superposed and attached 27. In this case, the front member 4 and the rear member 5 are attached 27 from the upper left and right sides to the lower edge of the side part, and the front member 4 and the lower part of the rear member 5 which are formed into a cylindrical shape by the attachment 27 are not attached. If the front side member 4 and the rear side member 5 are turned upside down, the top 27 of the skin member 3 in the normal state is attached to the lower edge of the left side part.
[0009]
Next, the unattached right and left edges 25 and 26 of the front member 4 and the rear member 5 are folded toward the left and right edges 23 and 24 of the already-attached 27, and the left and right edges 23 and 24 are already attached. 27, the right side edge 25 of the front side member 4 and the right side edge 26 of the rear side member 5 are overlapped and attached 29.
Also in this case, the front member 4 and the rear member 5 are attached 29 from the upper side of the unsewn portion in the middle of the left and right sides to the lower edge of the side portion, and although not shown in the figure, the attachment 29 forms a cylinder shape as described above. When the whole is turned upside down from the opening 28 in the lower part of the front member 4 and the rear member 5, the skin member 3 with the peripheral edge attached is obtained.
[0010]
Then, the stay 30 is mounted on the sewn skin member 3, the skin member 3 in this state is set in a mold, and the cushioning material is foamed and injected, whereby the perforated headrest 1 is completed.
In this case, the stay 30 may be attached while sewing each member around the stay 30, and the order thereof is arbitrary.
[0011]
Further, the lower edge 31 of the front member 4 of the embodiment and the front edge 32 of the lower surface member 9 are not sewn, but this portion becomes the opening 28, and when the cushion material is foamed and injected, the terminal is sandwiched by the cushion material. Processed.
In FIG. 1 to FIG. 3, the actual sewing portion is the inner side that cannot be seen from the surface, but in order to express the positional relationship, a reference numeral indicating the sewing portion is attached to the outer side of the headrest 1. Therefore, the sewn portion is not limited only by this code.
[0012]
[Action]
Next, the operation will be described.

The inner peripheral edge of the window hole 7 is overlapped with the rear peripheral edge of the cylindrical window inner peripheral member 8 and sewn 20.
Next, since the inner peripheral edge of the window hole 6 of the front member 4 is superposed on the front peripheral edge of the window inner peripheral member 8 facing upward and sewn 22, the back surface 11 of the front member 4 and the rear member 5 is in phase with each other. Oppositely, the front member 4 and the rear member 5 are not sewn on the periphery.
[0013]
In this state, the left side edge 23 and the left side edge 24 of the front side member 4 and the rear side member 5 are folded toward the right side edge 25 and the right side edge 26, and the left side edge of the front side member 4 outside the right side edge 25 and the right side edge 26. 23 and the left side edge 24 of the rear side member 5 are overlapped and attached 27, so that the front side member 4 and the rear side member 5 are attached 27 from the upper left and right middle to the lower side edge.
And since it becomes cylindrical by this attachment 27, it can be turned over from the opening part 28 of the lower part of the front side member 4 and the rear side member 5 including the part of the unattached front side member 4 and the rear side member 5, and right and left middle The skin member 3 that is attached 27 from the upper side to the lower edge of the left side is obtained.
[0014]
Next, the unattached right side edge 25 and right side edge 26 of the front side member 4 and the rear side member 5 are folded toward the left side edge 23 and the left side edge 24 of the already attached side 27, and the left side edge 23 and the left side edge 24 are already attached. 27, since the right edge 25 of the front member 4 and the right edge 26 of the rear member 5 are overlapped and adhered to the outside 29, the skin member 3 becomes cylindrical, and the peripheral edges of the front member 4 and the rear member 5 Are all dressed up.
Since the skin member 3 has a cylindrical shape, when the entire surface is turned upside down from the opening portion 28, the skin member 3 is attached with a peripheral edge.

The lower member 9 is turned over so that the front member 4, the rear member 5, and the lower member 9 all become the surface. Since it is a method of sewing the outer skin member of the perforated headrest, the number of times of sewing is small, and it is only necessary to sew the periphery with the back surface 11 of the front member 4 and the rear member 5 facing each other. There are few restrictions on the appearance design, and the degree of freedom can be improved. Since this attachment is made by superimposing the one side edges 23, 24 on the outside of the other side edges 25, 26, it can be done in a planar manner and is easy to speak. As a result, there are few wrinkles on the appearance after completion, and the effect of facilitating the attaching work can be achieved.
